“It’s clear to me he’s running for president — I don’t have any doubt about it,” Cummings told the Baltimore Sun.

Cummings said he and other Democrats spent the trip to South Africa for Nelson Mandela’s memorial debating with Cruz. “He got an earful from many of us — I mean it was a very good conversation, nothing negative,” he said. “I just reminded him that I’m concerned about the many people in my state and his state who have no health insurance.”

Added Cummings: “I know he got an earful for 20 hours out and he’s going to get another earful for 20 hours on the way back.”

The U.S. elected officials went to South Africa together as an official delegation.

Cruz made a name for himself when he spoke for 21 hours on the Senate floor, working to get people opposed to a government funding bill that included funding for the Affordable Care Act, also known as Obamacare.

Cruz, a senator out of Texas, is aligned with the Tea Party movement, and was born in Canada.
